A ball of radius s carries a charge density proportional to the distance from the origin. In other words, the charge density function is given by kx2+y2+z2. Find the total charge in the ball in terms of k and s. Hint: the integral of ∗ density over a region is the total ∗ in the region, no matter what ∗ is.

Consider the sphere with radius a shown below, carrying a uniform surface charge density ρS. a. Using Coulomb's law and integration, find the electric field a distance z from the center of the sphere. Treat the case za (outside). Express your answers in terms of the total charge Q on the sphere. b. Find the potential inside and outside of the spherical shell, directly by integration (similar to part a), and by using the electric field obtained in the previous part. Hint: Use the law of cosines to find the distance from the surface to pint P in terms of a, z, and θ(a2 + z2 − 2azcos⁡θ). Be sure to take the positive square root, that is, a2 + z2 − 2az = |z−a|

A ring of charge is centered at the origin in the vertical direction. The ring has a charge density of λ = 4.48×10−6 C/m and a radius of R = 2.01 cm. Find the total electric field, E, of the ring at the point P = (1.10 m, 0.00 m). The Coulomb force constant is k = 1 /(4πϵ0) = 8.99×109 N⋅m2/C2. E = N/C Find the expression for the electric field, E∞, of the ring as the point P becomes very far from the ring (x ≫ R) in terms of the radius R, the distance x, the total charge on the ring⁡ q, and the constant k = 1/(4πϵ0).
